Saudi dentist invents new dental surgery technique

Dr. Ali Thafeed Al-Ghamdi

By JEDDAH: ARAB NEWS Published: Mar 2, 2012 23:13 Updated: Mar 2, 2012 23:13

The Saudi dental consultant, who won international attention in periodontics and implant dentistry, has started practical application of his invention for the benefit of patients.

Head of the King Abdulaziz University Oral Basic and Clinical Sciences Department Dr. Ali Thafeed Al-Ghamdi, who is also assistant professor and consultant in periodontics and implant dentistry and head of periodontic department, received the copyright for his novel technique from the American Bureau of Patents and Inventions, the highest body for copyrights in the US, the Saudi Press Agency reported on Thursday.

Al-Ghamdi has also completed all experiments related to his inventions and wrote a final report on the surgical treatment. The new surgical technique developed by him and called Tunnel Technique will make considerable contribution to end difficulties countered while doing block graft surgery for diseased jaws, Al-Ghamdi said in a statement.

The new tunnel technique involves soft tissue preparation prior to symphyseal (fibrocartilaginous fusion between two bones) block graft.

His research reached a turning point when he noticed a fast healing tendency in patients who underwent allografts (transplant of cells, tissues or organs) for soft tissue augmentation prior to mono-cortical block graft compared to those who underwent the block graft before the allograft. That is why his research focused on allograft before block graft.

The sample patients underwent an acellular dermal matrix (ADM) allograft for soft tissue augmentation prior to mono-cortical block graft. The operated patients recovered without suffering any complications. On the other hand, three out of 10 people who underwent allograft after bone graft had developed several complications.

The success of the new technique was attested by a team of highly qualified dental surgeons who examined the patients who underwent allograft before bone

graft.

"The Tunnel Technique proves that Saudi doctors are not behind any other doctors in the world. This technique will contribute to minimize any complication during bone or jaw graft," Al-Ghamdi said.

He added that jaw and bone grafts are highly expensive and not every patient will be able to afford it.

Medieval Islam was a prosperous and dynamic civilization, and much of its prosperity was due to an engineering technology that assisted in increasing the production of raw materials and finished products. In addition, the demand for scientific instruments, and the need to cater for the amusements and aesthetic pleasures of the leisured classes, was reflected in a tradition of fine technology based upon delicate and sensitive control mechanisms.

This is a very wide subject indeed, and the Islamic contribution to the development of modern engineering will be indicated by means of citing individual cases of technology transfer.

Civil Engineering
Irrigation and Water Supply:

With the spread of the Islamic Empire westward, agricultural and irrigation methods and techniques were introduced into the western regions of Islam. The rulers of al-Andalus and many of their followers were of Syrian origin, and the climate, terrain and hydraulic conditions in parts of southern Spain resemble those of Syria. It is hardly surprising, therefore, that the irrigation methods - technical and administrative - in Valencia closely resemble the methods applied in the Ghuta of Damascus. [2]

There is a unanimous opinion among historians that the present Spanish irrigation systems of Valencia and Andalusia are of Muslim origin. In 1960 a celebration was held in Valencia commemorating the 'Millennium of the Waters'. It expressed public recognition of the establishment of the irrigation system, and specifically of the Tribunal of Waters during the reign of 'Abd al-Rahman III'.

The irrigation system that had been instituted in the days of the caliphs in Valencia was perpetuated and confirmed under the succeeding dynasties, until, when the Christian conquerors appeared in the thirteenth century, it recommended itself for adoption, backed by the experienced benefits of several centuries. The Arabic names used in the irrigation systems give distinct proofs of the Moorish origin of the irrigation systems in eastern Spain.

There is some difference between eastern Spain (Valencia and Murcia) and the kingdom of Granada. The chief object of the Granada water supply system was not the irrigation of crops only but the distribution of water to the fountains and baths of the capital. In Granada the system is still "to an exceptional degree" the same as it was in the time of the Arabs, and we find undisturbed the institutions practiced by the Arabs themselves.

An acequia flowing toward Granada from the spring in the village of Alfucar in the foothills of the Sierra Nevada, was first built in the 13th century and is still flowing today

The Arabic systems in irrigations were diffused from al-Andalus to Christian Spain. This accounts for the Aragonese traditions of irrigation.

These systems of irrigation had migrated from Spain to America where we find them still practiced in San Antonio in Texas. The story begins properly in the Canary Islands where in the late fifteenth century; settlers from Spain introduced Islamic institutions of water distribution. They brought with them to the American southwest both the technology and institutional framework for irrigation and the distribution of water.

The Qanat:

The qanat system was an efficient method for irrigation and water supply. It originated in pre-Islamic Iran. The qanat technology spread westward to North Africa, Spain, and Sicily. The Andalusi agronomical writers provide practical advice on well-digging and qanat construction.
From Spain the qanat technology was transferred to the New World and qanats have been found in Mexico, Peru, and Chile. In the 1970s a qanat system 2.3 kilometers long was located in the La Venta area, just 10 km northwest of Guadalajara, Mexico.
In Palermo, Italy, a qanat system from the Arab days was used to bring fresh water to the city and to irrigate its beautiful gardens. There are current plans to revive and reconstruct the Arabic qanat and utilize it to solve the acute needs of the modern city of Palermo for potable water. The project in hand is of great historical, archaeological, geological and hydro-geological importance. It is already of great interest for tourists.
